[Leiomyosarcoma of the temporal bone].

This is a report on a patient of 74 years of age presenting with ear pain and bleeding granulations on his tympanic membrane. X-ray of the mastoid revealed partial destruction of the bone structures and reduced pneumatisation. A tumour that was mainly located in the temporal bone was surgically removed and proved to be a leiomyosarcoma. This is the first case of a leiomyosarcoma of the temporal bone to be described. Differential diagnosis and therapy of this tumour are discussed.
